Brick slip sealer in kitchen

[NewToTiling2025]

Hi, I hope someone can help. I had brick slips put up in my kitchen and the tiler that installed them has covered them with a sealant called LTP mattstone. I was told it would be perfectly fine in the kitchen, even on the splashback but since he has applied it I have been so sick everytime I've walked in the kitchen. My chest is burning, I feel nauseous, weak and shaky. I don't know if I'm just sensitive to it or if this stuff is too strong to use in the kitchen. How do I get rid of it? I'm thinking about ripping it all off which will mean I've wasted thousands but I feel so sick. I hope someone has some advice 🙏

The smell should go once dry. Well ventilate the room

Thanks for replying. Is it toxic to have in the kitchen? What can I do to remove it from the brick slips?

It’s solvent based hence the smell. It normally goes once dry. Were they sealed again after pointing ?
